hello everyone, he is a barred rock about year and 1/2 old -- he is so nice ! he even stops and wants to be picked up -- I noticed him with some heavy breathing but after reading about this I can't find any thing that mention a cold comb. Any one has information about it? He is eating OK and drinks his water so i have him separate to keep warm, all I did so far is put some Save a Chic powder in the water .... Thanks!!
